IPC: H01L27/112
Filed: 1987-04-02
Abstract: PURPOSE:To perform low power consumption writing and high speed reading, by supplying a writing current at a constant current characteristic, and controlling the writing current with a resistance load characteristic. CONSTITUTION:A writing control transistor Q6 and a power-source current supplying transistor Q7 are made to be P-channel enhancement type transistors. A drain-source current IDS is divided into a non-saturated region from O to A, a saturated region from A to B and a diode characteristic region from B to C as in an N-channel enhancement type transistor. Of these regions, the saturated region, in which a gate voltage VGS is constant, i.e., a constant current characteristic, is utilized. Furthermore, a channel width W of a bit-line selecting transistor Q5 is made large and resistance is decreased. This becomes possible by limiting a writing current with said constant current characteristic. Thus, high speed writing becomes possible, low power consumption writing can be performed and high speed reading becomes possible.

Title: Method of controlling transmission for vehicle
Inventor: TAKADA MITSURU
IPC: B60W10/101
Filed: 1985-04-17
Abstract: PURPOSE:To prevent speed change shocks by determining the gear stage changing-over the region of an auxiliary transmission on the basis of the actual required output of a vehicle and speed change ratio of a step-less transmission. CONSTITUTION:When a shift lever is operated from L range to D range, the gear ratio of a transmission is allowed to be changed over when the actual speed change ratio r is smaller than than a predetermined value r1 (theta, v) and said gear ratio is smaller than a certain value in which speed change shocks hardly occur. Also, when the shift lever is operated from D range to L range, the change-over is carried out if the speed change ratio of the input side rotary shaft of an auxiliary transmission corresponding to vehicle speed v is smaller than a value in which the speed change shocks are not intensified. Thus, the gear stage of an auxiliary transmission 14 is changed over under the maximum condition corresponding to the speed change ratio of a step-less transmission 12 to prevent the speed change shocks.

Abstract: PROBLEM TO BE SOLVED: To have an effect on brake deceleration in operating condition of emergency braking by controlling deceleration of a vehicle by control of braking force according to a preset value of the deceleration depending to the operating amount of a brake pedal, and forming the preset value depending on the operating condition of the control of a brake device. SOLUTION: An operating signal of a brake pedal is detected by a micro computer 16 through an input conductor 22 in a control device 10. This signal is represented by pressure effected by a driver in an area of a main brake cylinder of a hydraulic brake device 12, that is approach pressure. If this approach pressure exceeds a designated threshold value and larger than grade threshold value, brake pressure is generated independent from the driver by corresponding drive of a valve device of wheel brakes 40, 42, 44, 46 and a pump device resulting from panic condition. Brake pressure increases to attain max. friction coupling between a tire and a road. This is caused at a reference value of set vehicle deceleration to be set to a maximum value in a driving step.

Title: Word processor
Inventor: TSUAKI HAJIME
IPC: G06F17/21
Filed: 1986-04-10
Abstract: PURPOSE:To prevent a system control circuit from runaway by permitting the system control circuit to detect a drop in a battery voltage, stopping the execution of a system program at the time of the detection, storing the detected result in a detected result storage circuit and feeding back the storage contents to the system control circuit. CONSTITUTION:When a battery 1 is further consumed to drop its voltage, the system control circuit 5 stops the execution of the system program, simultaneously outputs a voltage drop detection signal Sk0 and stores the voltage drop detected result in the detected result storage circuit 14. Consequently the further drop in the voltage of the battery 1 can be prevented. If a voltage VB rises, the storage contents are fed back to the system control circuit 5, and therefore the circuit 5 can inhibit a main mechanism part 6 from driving based on the stored result. Thus the battery 1 can be used up completely. Moreover if the voltage of the battery 1 drops, the runaway of the system control circuit 5 can be eliminated by stopping the execution of the system program.
